Time Domain Analysis

Abstract

Under Contracts F30602-72-C-0027 and F30602-73-C-0070, Pattern Analysis and Recognition (PAR) Corporation has designed and simulated a six-class classifier for identifying targets of tactical interest based on their acoustic signatures. The classes are: wheeled vehicles, tracked vehicles, propeller aircraft, rotary aircraft and jet-powered aircraft. Background is rejected to prevent false alarms. Design or training set recognition rates on data collected by RADC/OCDE under a wide variety of environmental conditions was 100%. Limited preliminary testing of the simulated classifier has also yielded 100% results.
